CARL HENRIKSSON, OF STOCKHOLM, SWEDEN, ASSIGNOR TO AKTIE- BOLAGET S. HENRIKSSONS SPRUTFABRIK & MEKAMISKA VERK- l Specification of Letters Patent.

Patented Dee. 25, 1906.

Application filed August 1, 1906. l Serial No. 328.786.

To @ZZ whom t may con/cern:

Be it known that I, CARL HENRrxssoN, ,a subject of the King of Sweden, residing in Stockholm, Sweden, have invented certain new and useful Improvements in Wheeled Trucks, of which the following is a specification. i

This invention relates to wheeled trucks with receptacles for collecting refuse on streets, such as are provided with a pan disposed in front of the upright receptacle ,or body of the truck and carried bythe frame of Uthe device, said pan being mounted to swing about journals in such a manner that it cani be lowered to the ground by a lever to a position where the refuse, dirt, &c., may be sweptinto it and then raised to a position above the receptacle for dumping its contents into the same. `So far as known to me in Ytrucks for this purpose the operating-lever has been "so disposed that the lifting of the pan is apt to move the vehicle along the roadway, as its `and others, as will be hereinafter explained.

In the accompanying drawings, which serve to illustrate an embodiment of the invention,

' Figure 1 is a side elevation' of the vehicle, the

pan being represented in full lines as'resting on the ground, and in its elevated -or discharging positionit is represented in dotted lines. Fig. 2 is a plan of the vehicle. Fig. 3 is a front elevation showing the pan in its elevated. dumping position. Figs. 4 and 5 are-detail views on a larger scale. These will be hereinafter described.

The receptacle or body 1 is mounted removably at two points on the bent axle 2 of the vehicle, the bail-like handle 3 being secured iirmly to the axle and provided with legs 4, as seen in Fig. 1. These legs are formed of bent bars, as clearly shown in this figure.

` The pan 5, which is somewhat in the nature of a dust-pan or shovel, is connected lwith a cross-shaft 6, journaled on the bars of the4 handle 3 at a point near the axle 2, the connection being through two bent arms 7, which are fixed at one end to the shaft 6 and at the plan, as here shown,) this curved bar 91embracing the pan and pivotally connected thereto at its respective ends by trunnions 8. A link 10, connecting the rear margin of the pan with a iixed part 11, determines the inclination of the pan, Fig. 1, when it rests on the ground when elevated to the dumping position and during its'movements.

The Amovements of the pan 5 are effected by means of a lever 12, the free end of which is in the nature of a treadle to be operated by the foot. The lever isfulcrumed at 16 to one of the legs 4 and is coupled to the shaft 6 for rocking the latter through the medium of a link-and-lever mechanism so constructed that the depression ofthe lever serves both to lower and to raise the pan 5.

Referring especially toFiO's. 4 and 5 for illustration, it will be noted that the shaft 6 has on it a crank-arm 13, which is connected to the lever 12 through the medium of a long link 15 and a' shorter link 14. The upright or elevated position of the arm 13 (seen in Figs. 1 and 5) is that taken when the pan 5 rests on the ground, and the dependent position of this arm (seen in Fig. 4) is that assumed when the pan 5 is in its elevated position. In the present position of the parts (seen in Fig. 5) a toe 17 ,fixed to the crankarm 13, bears on link 15 and holds the links 14 and 15 in the elevated position shown, so that` the link 15 will rock the shaft 6 in the direction sh'own by the arrow when the lever other end to a curved bar 9, (semicircularin 12 is depressed. In the position ofthe parts seen in Fig. 4 a, toe '20, rigidly connected with the link 14 and bearing on the shaft 6, holds the link 14 projected forward, as seen in this Fig. 4, whereby pressure upon ythe lever -12 will rock the shaft 6 in the direction indicated by the arrow in this figure. As the pan 5 is lowered, the link 10 holds and presents it in the proper oblique or inclined position that is most suitable for receiving the sweepings.

When the parts are in the position seen in Fig. 1, downward pressure on the lever 12 rocks the shaft 6, as shown in Fig. 5, the arms 7 being consequently swung u ward and the pan 5 brought thereby into t e positionindicated by the, dotted lines in Fig. 1,

the bowl-shaped part 18 of the pan being inverted over the receptacle 1 and emptied into the latter through the action of the link IOC vdumping.

10 and the flat end or lip 19 of the pan l the pan rigidly with said shaft, an operatingbrought to rest on the margin of the receptacle 1. like a cover. During this movement the pressure on the lever 12 must be maintained until the pan shall have passed by its center of rotation at the shaft 6, when it will automatically continue in its movement through the force of gravity, so that only a slight retarding pressure on the lever, which will then be'moving upward for a little distance, generally su'lrices to control the descent of the inverted pan onto the receptacle 1. During this movementthe toe 20 iinally comes in contact with the shaft 6 and brings the link 14 into the position seen in Fig. 4, in which position the momentum oi thelink 1'5 suHices to cause the pan to drop when pressure is again exerted on the lever 12. -Also by the pressure last mentioned the pan .is at irst moved past the center of rotation at the shaft 6, whereupon said pan descends to the ground, being actuated by gravity, while the pressure on the lever 12 is correspondingly reduced.

in order to guide it in its movements, the

:lever 12 may have a slot formed in it, as indicated at `21 in Figs. 2.and 3, so that it embraces and plays over the leg 4 at that side. The `entire apparatus or device described will be supported on wheels 22, turning on the axle 2. either by the hand or the foot. is most convenient, the lever is shown herein asadapted and shaped so as to be operated best bythe Jfoot. ally descend and rest on the receptacle 1in It is only necessary that it shall be ybrought to the dumping'- position. The bars forming the legs 4 and the U-sh-apedbar .forming the handle 3 constitute a frame and together with the bent axle and the wheels constitute a support for the operative `parts .and ther-eceptacle.
